Hugging the World's Most Beautiful Younger Sister While Sleeping Somehow Turned Her into a Yandere - 11 - Confrontation

“So… who is that girl?”

Returning from shopping, Aoi was greeted by Runa with a disdainful look.

It’s understandable if she looks at her brother being friendly with a cute girl with a bit of contempt.

Runa, visibly in a bad mood, puffed her cheeks and seemed jealous of Minami, who was with them.

Due to her displeased mood, Runa wasn’t putting away the groceries in the kitchen.

“Minami is my childhood friend.”

“I’m Minami Shindo. Huh? What’s up with those looks? There is really someone so beautiful in reality?”

After introducing herself, Minami seemed surprised, as if she were admiring a work of art, gazing at Runa.

While it’s natural for Runa to be admired as the most beautiful girl in the world, being looked at in such a way was probably unpleasant for her.

“You had a childhood friend, Nii-san? It’s the first time I’m hearing about this.”

They were together before their parents remarried, so it’s natural that Runa doesn’t know about Minami.

“She moved away. She came back recently and will be attending the same high school from next week.”

“I see.”

Despite getting along well as siblings recently, Runa responded with a distant tone, seemingly dissatisfied.

I thought of saying, “Onii-chan is sad,” but Minami’s words interrupted me.

“Are you two siblings? I didn’t think you had a sister, Onii-chan.”

“Our parents remarried, making us siblings.”

“I see, I see. So, she’s not your girlfriend, right? I’m relieved.”

Minami, smiling warmly, glanced at the seemingly upset Runa.

It might be just an illusion, but it seems like sparks were flying between Runa and Minami.

Maybe Minami has sensed that Runa is a brocon.

Aoi hoped that they, his step-sister and sister-like childhood friend, would get along.

“I’m Aoi’s younger sister, Runa. If you’re not dating him, could you stop clinging to him? Aoi won’t be pleased with such small things.”

“Aw, even if I stick to Onii-chan, it’s not something Runa-chan should be concerned about, right?”

Apparently, the step-sister and sister-like childhood friend are incompatible, their gazes clashing intensely.

Minami’s breasts are by no means small and very soft, but they are inevitably inferior to Runa’s larger ones.

“I don’t value a woman based on her breasts’ size……”

He has never cared about breasts and such, because it doesn’t matter if they’re big or small. In the first place, because he loves Runa so much, he thinks nothing of Minami’s pressing of her br***ts against him.

It wouldn’t be an exaggeration to say that he is standing at the pinnacle of sister complex.

“I made a promise with my brother to get married in the future. It’s a promise we made as childhood friends who are like siblings.”

Certainly, there is a memory of making such a promise in the past, but I didn’t expect her to bring up a story from kindergarten.

We used to be very close, often having sleepovers and naturally talking about getting married in the future.

“That’s just a story from kindergarten, right? I sleep with Nii-san every day now.”

No need to compete, I wanted to retort. Moreover, the recent development of sleeping together is just a matter of the past few days, so saying “every day” was incorrect.

“I think it’s strange for high school siblings to sleep together. For me, it’s okay because we’re childhood friends. Even if a mistake happens, right?”

As if tempting, Minami tightens her grip on the arm.

press, Minami’s soft breasts pressed against his arm, and Aoi realized that she was in love with him. 

No matter how close we had always been, if she didn’t like me, she wouldn’t press her breasts against my arm when we are in adolescence.

At first I thought it was because she was coy, but I knew she wasn’t because of the blush on her cheeks and the embarrassment.

I guess she was able to do it because it’s someone she likes. 

“Muu……Nii-san is a siscon, so it’s futile for a childhood friend to try to seduce him.” 

“Is that so? But, I’m like a little sister to Onii-chan, so it’ll work out just fine.” 

“No, it will not. Because Nii-san loves me.”

Maybe to counter, a blushing Runa also entwined her arms around me.

She made embarrassed sounds, like “Aau~” and pressed her large chest against me.

“Why am I becoming a romantic-comedy protagonist?” 

Even though I muttered such things, the confrontation between Runa and Minami never ended.
